APEX

On the login page, I am wrapping wwv_...std.login API call inside an anonymous block. That anonymous block raises an exception through raise_application_error.That error is displayed automatically on a separate page(I don't know which page is this). But that page also displays username in the footer. This is the username that I used to login at the login screen. How can I avoid displaying user name at that error page?

Also, how does this username gets set? I thought that wwv...std.login API sets App_user substitution string and thats how username gets displayed through page template. But in my case, when exeception gets raised even before login API is called, then how does app_user gets populated?

PS: I don't want to remove username display from every page once user successfully authenticates.


Thanks a lot!
